Measures the magnitude and phase of the induced currents, which are related to the subsurface electrical conductivity, at different frequencies. System options include multi-frequency EM sensors to map conductors at shallow depths and a horizontal loop EM system for deeper applications, like groundwater and mining exploration.

Multi-frequency EM sensor for shallow investigations. Sensor is configured for both ground and UAV surveys.
Multi-frequency, multi-spacing HLEM system for sounding and profiling. Available with 1 or 3 components.
